Midibox NG Led Digit

[All2u]

Hello there,

 

I have made a pcb for 10 led digits but the problem is that all the led digit have the same number !!

 

When I upload in mios the leddig2.ngc and I'm play with the cc64 to cc73 all the numbers is changing at the same time...

 

Is someone have the same problem ? it's very boring.

 

I join a photo of the problem and an image of my pcb design, if anyone would like the eagle file no problem.

 

 

(sorry for my english I'm french)

 

Thank you in advance

 

Best regards.

It seems that you are using LED digits with common anode (my examples are pre-configured for common cathode devices).

 

So, instead of:

# HW definitions for "Common Cathode" Digits
# see also http://www.ucapps.de/midibox_ng/mbng_led_digits_mtc.pdf
DOUT_MATRIX n=1   rows=8   sr_dout_r1=1  inverted_row=0  mirrored_row=0  sr_dout_sel1=2  inverted_sel=0
DOUT_MATRIX n=2   rows=8   sr_dout_r1=3  inverted_row=0  mirrored_row=0  sr_dout_sel1=4  inverted_sel=0

just write:

# HW definitions for "Common Anode" Digits
DOUT_MATRIX n=1   rows=8   sr_dout_r1=1  inverted_row=1  mirrored_row=0  sr_dout_sel1=2  inverted_sel=1
DOUT_MATRIX n=2   rows=8   sr_dout_r1=3  inverted_row=1  mirrored_row=0  sr_dout_sel1=4  inverted_sel=1

Hello,

 

I've already changing the configuration and it's not working !! all the digits says 8.

So with common cathode it's display numbers changing with CC but on all the digits at same times.

 

I hope I've been clear because it's frustrating... if not I could make a video for more explicit !!

 

Thank you for your help

 

Best regards, Laurent.

Sorry it's working !!!!

 

I don't know why but It's alive again,

Anyway the problem seems to be in cubase the led digits don't react at the MTC.

 

Anybody knows why ?

 

Thank you,

 

Best regards, Laurent.
